Quadrilaterals

Stage: 2 Challenge Level:

How will you record the quadrilaterals you've made? You might like to print off this sheet to use.
You could try drawing quadrilaterals which have a side made by joining two pegs next to each other. How many different quadrilaterals can you make in this way?
How will you know when you've got them all?

The NRICH Project aims to enrich the mathematical experiences of all learners. To support this aim, members of the
NRICH team work in a wide range of capacities, including providing professional development for teachers wishing to
embed rich mathematical tasks into everyday classroom practice. More information on many of our other activities
can be found here.
